Great discussion John and William, thank you for it. John, that is actually my original question I guess, just why DID they change from a spring to a tab? It sure was not for cost control, the tab is a far more complex system than the spring, which had apparently served the coupes well for many aircraft with no complaints. Those of you who have flown both types, you comments are welcomed. I don't mind changing mine over to the more conventional trim tab, if I can uncover one shred of indication why I would want to (other than the airworthines issue). I am not even certain that my plane has been converted to 85hp, since it has no trim tab, I am judging mostly by the remarked oil dipstick, and a new blank engine tag that came with the plane..
